Simplifying x2 + -20x + 14 = 0 Reorder the terms: 14 + -20x + x2 = 0 Solving 14 + -20x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-14' to each side of the equation. 14 + -20x + -14 + x2 = 0 + -14 Reorder the terms: 14 + -14 + -20x + x2 = 0 + -14 Combine like terms: 14 + -14 = 0 0 + -20x + x2 = 0 + -14 -20x + x2 = 0 + -14 Combine like terms: 0 + -14 = -14 -20x + x2 = -14 The x term is -20x. Take half its coefficient (-10). Square it (100) and add it to both sides. Add '100' to each side of the equation. -20x + 100 + x2 = -14 + 100 Reorder the terms: 100 + -20x + x2 = -14 + 100 Combine like terms: -14 + 100 = 86 100 + -20x + x2 = 86 Factor a perfect square on the left side: (x + -10)(x + -10) = 86 Calculate the square root of the right side: 9.273618495 Break this problem into two subproblems by setting (x + -10) equal to 9.273618495 and -9.273618495.Subproblem 1
x + -10 = 9.273618495 Simplifying x + -10 = 9.273618495 Reorder the terms: -10 + x = 9.273618495 Solving -10 + x = 9.273618495 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '10' to each side of the equation. -10 + 10 + x = 9.273618495 + 10 Combine like terms: -10 + 10 = 0 0 + x = 9.273618495 + 10 x = 9.273618495 + 10 Combine like terms: 9.273618495 + 10 = 19.273618495 x = 19.273618495 Simplifying x = 19.273618495Subproblem 2
x + -10 = -9.273618495 Simplifying x + -10 = -9.273618495 Reorder the terms: -10 + x = -9.273618495 Solving -10 + x = -9.273618495 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '10' to each side of the equation. -10 + 10 + x = -9.273618495 + 10 Combine like terms: -10 + 10 = 0 0 + x = -9.273618495 + 10 x = -9.273618495 + 10 Combine like terms: -9.273618495 + 10 = 0.726381505 x = 0.726381505 Simplifying x = 0.726381505Solution
The solution to the problem is based on the solutions from the subproblems. x = {19.273618495, 0.726381505}
